Abstract
The utility model relates to an adjusting tensioning mechanism of a middle pulley, which relates to the adjusting tensioning mechanism of the middle pulley used for the long distance transmission of a belt and belongs to the technical field of belt transmission. The utility model is mainly composed of the belt, a driving pulley, a driven pulley, the middle pulley, a bearing, an adjusting bottom base, a bottom base support, an axle, etc., wherein, the middle pulley and the bearing are fixed on one end of a crank axle and the other end of the crank axle uses a hole matched with the crank axle and arranged on the adjusting bottom base to enable the middle pulley and the bearing to be fixed together. The inner part of the hole for installing the crank axle on the adjusting bottom base is inlaid with a copper sleeve. The adjusting bottom base is provided with an axle elastic blocking ring used for preventing the crank axle from being disconnected from the adjusting bottom base and clamped on the crank axle. Both ends of the hole of the adjusting bottom base are respectively provided with an O-shaped sealing ring and a metal sealing cover. The utility model enables the belt tensile forces on the two sides of the middle pulley in the long distance transmission of the belt to be equal. The utility model also has the advantages of reasonable structure, stable performance, convenient adjustment, low cost, etc.
Description
(1) technical field
When the utility model related to a kind of belt length apart from transmission, the adjustment tensioning mechanism of the counter pulley of use belonged to the belt transmission technical field.
(2) background technique
Belt transmission is one of type of belt drive of the most normal use in the mechanical industry.When belt carries out the transmission of longer distance,, use intermediate belt crop rotation transition transmission usually for increasing bel-drivenn stability.The mechanism of the most normal use at present mostly be with counter pulley and bearing fixing one with axle on, axle is fixed on the adjustable bearing, by adjusting base the belt of counter pulley both sides is carried out tensioning.The problem that this structure exists be counter pulley adjust bearing fixing after, the tension force of its both sides belt can not guarantee identical fully, mechanism also can't adjust the tension force of counter pulley both sides belt in running automatically, the belt of counter pulley both sides is moved under the different condition of tension force, so stressed difference of belt, its degree of wear difference, the life-span is also different.Because the belt of counter pulley both sides all can not be worked under normal operating conditions, makes the life-span of belt also not reach its normal working life, phenomenons such as early fracture appear in belt, cause very big waste to the user.
(3) summary of the invention
The utility model is for remedying the deficiencies in the prior art, and providing a kind of can during apart from transmission, make the both sides belt tension of counter pulley identical in belt length, and tensioning mechanism is adjusted in rational in infrastructure, stable performance, a kind of counter pulley easy to adjust.
The utility model is realized by following technical measures:
The utility model mainly is made up of belt, drive pulley, driven pulley, counter pulley, bearing, adjustment base, base support, axle etc., wherein, counter pulley and bearing fixing are at an end of bent axle, and the other end of bent axle is fixed together both by adjusting the hole that cooperates with bent axle on the base.
On adjusting base, embed copper sheathing in the hole of installation bent axle.
The circlip for shaft that prevents that bent axle from deviating from from adjust base is set on adjusting base, and is stuck on the bent axle.
Be respectively charged into O-ring seals and metallic sealed cover at the two ends of adjusting base aperture.
The utility model is provided with bent axle makes the belt maintenance tension force of counter pulley both sides identical, for bent axle is rotated freely, on base, embed copper sheathing in the hole of installation bent axle, and be stuck on the bent axle with circlip for shaft, deviate from from base to prevent bent axle, be the rotation that prevents that impurity such as dust from entering influences bent axle between bent axle and the copper sheathing, be respectively charged into O-ring seals and metallic sealed cover at the two ends of base aperture.Working principle of the present utility model is: after the adjustment base makes belt tension, determine of the operation of the position of counter pulley along with mechanism, bent axle can be around center, the hole swing of having inlayed copper sheathing on base, and adjust the tension force of counter pulley both sides belt automatically, make the tension force of counter pulley both sides belt remain unanimity, can guarantee that like this life-span of belt is basic identical.Use the utility model effectively to solve when belt length is apart from transmission in the prior art, the different problem of counter pulley both sides belt tensile force, and have and rational in infrastructure, stable performance, easy to adjust, low cost and other advantages.
